A Guide to Avoiding the Most Common RCT & VAT Pitfalls for Non-Resident Principal Contractors

An area that has continued to cause challenges and risks for businesses is the operation of Relevant Contracts Tax (RCT) and VAT.

The most common mistakes we see being made in this sector are by non-resident principal contractors who engage a subcontractor to carry out construction works in Ireland.

This article will focus on the most common pitfalls that we see occurring within this sector by non-resident principal contractors and the steps that can be taken to avoid making costly mistakes.

1. Compliance Obligations for Non-Resident Principal Contractors

When a non-resident principal contractor engages a subcontractor to carry out construction works in Ireland, the RCT system must be applied to payments made to the subcontractor.

The first potential pitfall for a non-resident principal contractor is not taking the reasonable care to familiarise themselves with their tax obligations under the RCT regime. In such a case, the non-resident principal contractor will eventually be contacted by Revenue, informing them of their failure to operate the RCT regime. This usually occurs following the commencement of the works in Ireland, at which point the mistakes have already been made and costly penalties can be imposed by Revenue.

As such, it is very important that a non-resident principal contractor is aware of their tax obligations prior to the commencement of any construction works in Ireland so that the necessary administrative steps can be taken to ensure that they are set up for the RCT system and fully compliant in operating RCT on payments to subcontractors.

The administrative steps to be taken by a non-resident principal contractor include registering for RCT on Revenue’s Online Service (ROS) and operating the RCT regime throughout the duration of the project in Ireland (further detail on this below).

2. Operation of the RCT System

Once a principal contractor is registered for RCT with Revenue, there are a number of steps that must be taken each time a principal contractor enters into a relevant contract with a subcontractor and each time a payment is made to the subcontractor. These steps are summarised as follows:

a. Contract Notification

• The first step is to input a “Contract Notification” through Revenue’s online RCT system. A principal contractor must notify Revenue each time it enters into a new relevant contract with a subcontractor. The Principal will then receive a contract reference number and an indication of the applicable RCT deduction rate for the subcontractor.

b. Payment Notification

• Before making a payment to a subcontractor, the principal must notify Revenue’s online eRCT system of the intention to make the payment and provide details to Revenue of the gross amount to be paid. This process is known as “Payment Notification”. This must be done for each payment made to the subcontractor.

c. Deduction Authorisation

• Revenue will issue a deduction authorisation to the principle contractor which will specify the rate and amount of tax to be deducted from the payment to the subcontractor. This process is known as “Deduction Authorisation”. The principle is required to provide a copy of this authorisation to the subcontractor.

d. Deduction Summary (RCT Return)

• Revenue’s eRCT system prepares a pre-populated period end return known as a “Deduction Summary (i.e. RCT Return)”, which is based on the deduction authorisations issued during the period. The due date for payment of the RCT withheld is the 23rd day after the end of the period covered by the return.

The most common pitfall we see occurring in practice are inconsistencies in notifying Revenue of each and every payment made to a subcontractor by the principal contractor. This can be a costly mistake for the principal contractor as the penalties Revenue can impose for failure to operate the RCT system in this way range between 3% to 35%, depending on the RCT deduction rate applicable to the subcontractor.

To put this into perspective, if a subcontractor has been assigned a 35% RCT deduction rate and the principal contractor makes a payment of €25,000 to the subcontractor without first notifying Revenue of the payment and deducting the appropiate withholding tax, Revenue can impose a penalty of €8,750 (i.e. 35% of the invoice value) on the principal contractor for its failure to operate the RCT system.

These penalties can become very costly for a business where they fail to operate the RCT system on high value invoices.

3. Operation of RCT and Reverse Charge VAT

Typically, VAT is normally charged by the person supplying the goods or services. However, under the RCT regime, the person receiving the goods or services (the principal contractor) calculates the VAT due on the invoice from the subcontractor and pays it directly to Revenue. This is referred to as Reverse Charge VAT and it is common area in which mistakes are made by non-resident principal contractors.

The following should occur when a subcontractor invoices a principal contractor for construction services that are subject to RCT:

1. The subcontractor raises an VAT invoice with the zero rate of VAT applied;
2. The invoice should include the VAT registration number of the principal contractor and include the narrative “VAT on this supply to be accounted for by the principal contractor”;
3. The principal contractor calculates the VAT due on the invoice value and records it as VAT on sales (Box T1) on its VAT return. Where it is entitled to do so, the principal contractor can claim a simultaneous VAT input credit (Box T2) on the VAT return, thus resulting in a VAT neutral position.

Although the RCT system can seem like a heavy administrative burden on a business, it can be managed relatively smoothly with the proper administration. Our tax specialists look after all administrative issues regarding RCT, provide effective advice and answer questions you may have regarding RCT.
